Creating a OneSignal Account

If you are a returning user, use your existing credentials to login to your OneSignal account. You can create multiple app entries under the same account.
If you need to create a new account click the Sign Up button down the bottom of the pop-up window
Fill in your details and Confirm your account
Once your account has been confirmed you can login to your OneSignal account and begin setting up push notification for iOS and Android.

Adding a new app

Go to OneSignal website
Click Login. If you have a OneSignal account you should login - if not register an account.
Once logged in - you will be able to Add a New App. Click Add a New App.
Name your app appropriately and click Create
You have now created a new app entry to send push notifications to. You can now configure your app for Apple and Android push notifications. You may close the pop-up screen or continue.

iOS: Production .p12 creation

To enable iOS push notifications, you must export your iOS push notifications certificate as a production .P12 file, then upload this file to OneSignal.

If you haven't already created your iOS push notifications certificate, see the the relevant instructions in iOS Certificates, Identifiers, and Profiles.

You can only modify your push notifications certificate on the Mac computer it was originally created on.

Exporting your Push Notifications Certificate as a .P12

After creating your push notifications certificate and adding it to your Mac computer's Keychain, open the Keychain Access application.
Select the login keychain, and the Certificates category. Identify your push notification certificate.
The certificate should be identifiable by its name, and the date on which it expires (one year after creation).
Hold the control key and click on your push notifications certificate. In the menu that appears, choose to Export your certificate.
Save the exported certificate as a .P12 file type. This is extremely important, as parse.com will only read .P12 files. As per usual practice, save the .P12 file with an easily identifiable name, in a memorable location.
Next, two dialogue boxes will appear. In the first box, you will be asked to create a password to protect your .P12 file – do not enter a password here.

Leave both fields blank and click the OK button. Again, this is extremely important as parse.com will not be able to access your certificate if you enable password protection.
The second dialogue box will ask for your computer's system user password. Go ahead and enter your password here, then click Allow to finish exporting your certificate as a .P12.

You now have a modified .P12 certificate.

Next, you will upload this file to OneSignal.
